TB! is visible in the in the uninstaller from a second user (admin rights as well) ; there are TB! entries in the registry as well (I didn't compare them) but I think the main entry of RIT is not here (user dependant). The values that looks responsible for not allowing a new installation are under: HKEY_CURRENT_USER (assuming that). So it should be possible to remove HDD database and RIT entry from registry for a currently logged user and do not affect other users (it's probably more than 99% of situations). Need to think about that. -- Best regards, RS The Bat! 5.0.8 Windows7 Professional (x64) Polish (SP1) OTFE Enabled ; so far only 3 POP3 accounts The Bat! 5.0.10 Windows7 Ultimate (x64) English (SP1) OTFE Enabled ; so far only 3 POP3 accounts ________________________________________________________ Current beta is 5.0.12.1 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
